LUBRICATING JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 617,817, dated January 17, 1899. Application filed July 9,1898. Serial No. 685,480. (No model To all whom, it may concern Be it known that I, ALBERT 0. SMITH, a citizen of the United States of America, and a resident of Saco, in the county of York and State of Maine, have invented certain Improvements in Lubricating J ournal-Boxes, of which the following, read in connection with the accompanying drawings, is a specification.

This invention has for its object to provide means for retaining oil in connection with revolving journals and other moving parts of machinery.

In the accompanying drawings this my invention is illustrated and shown in different conditions of use.

Figure 1 shows the device with a bearingface adapted for use in car-axle boxes or where the moving part is circular. Fig. 2 is an elevation of a cross-section of a car-axle and box embodying this form of the invention. Fig. 3 is an elevation of a cross-section of an engine cross-head with this form of my in vention'applied thereto. Fig. 4 shows the device with a flat bearing-face designed for usein cases where the moving part is a flat surface. Fig. 5 shows the improvement applied to an engine crank-pin and is a sec-.

tional View onthe line a: w of Fig. 6. Fig. 6 is a vertical section on line y y of Fig. 5.

This invention comprises a metal blank or plate 2, which preferably is made of brass and is provided with an under bearing-face 3, designed for resting on the intended journal or work part, in sliding contact therewith. Surrounding the bearing-face 3 is a gro0ve5 in the material of the plate, and in the groove 5 is a packing 6, Which may be of hemp, cocoanut fiber, or other suitable oil-excluding material. The packing 6 is allowed to project from the groove 5, so that when the plateis applied in working use with its bearingface 3 on the intended journal or machine part the packing 6 will be compressed tightly against the said journal or machine part and exclude oil from passing through between The margin of plate 2 outside of the packing is cut away or rabbeted, as at 7, so that this part of the face shall not bear in touch with the surface ofthe journal or moving part, all this to avoid the possibility of the plate becoming overheated by any dry friction between the parts. working face with oilreceiving grooves 4, whichopen through the bearing-face 3. Instead of grooves a series of holes or cavities of diiferent shape maybe employed. In use the oil is introduced into these grooves or cavities in quantity and will pass therefrom onto the surface of the journal or moving part as required for use. An opening 8 may be provided through which to introduce the oil from outside into the groove tor cavities, and, if desired, this opening may be extended from an oil pot or receiver outside the plate 2.

When used in a car-axle box, thedevice is made to take the place of the ordi'narycaraxle brass, and to that end the plate 2 is made with the form of such a brass and interposed with its bearing-face on the axlesurface, as shown in Fig. 2. Other component parts of the axle-box, being of the usual and well known construction, are not described.

\Vhen used in the engine-cross-head mechanism, the plate 2 has a flat bearing-face and is interposed with its bearing-face on the surface of the part or way whereon the crosshead slides, as shown in Fig. 3, other parts of the cross-head shown being of the usual and wellknown construction.

In Figs. 5 and 6 two of the plates 2" arerepresented having semicircular bearingfaces arranged on opposite sides of an engine crank-pin, with an open space between to allow for taking up in the usual manner of compensating for wear.

The several plates 2, 2, and 2 are all provided in their working faces 3 with the oil? conducting grooves or cavities 4, exterior to which the said working face is provided with the packinggroove 5, which incloses "the grooves 4 both at the sides and ends of the plate, so that when the oil-excluding packing is in place no oil can pass therebeyond. Moreover, the rabbet 7 extends around the The plate 2 is further provided in its entire margin of all of said plates, so that no non-lubricated portions thereof will'come in contact with the journal, pin, or other moving part.

Obviously from the foregoing description this invention may be modified and applied.

by ordinary mechanical skill to the moving parts of other machines.

I claim as of my invention and by Letters Patent desire to secure- 1. A plate for the purposes described pro-.

vided in its working face with oil-conducting grooves vor cavities having communication with the opposite side of the plate, a packinggroove in said working face beyond and completely inclosing or encircling the oil-con ducting grooves or'cavities; which packinggroove has no communication with the opposite sides of the plate; whereby when the said groove is packed as described no oil can escape beyond its sides or ends; substantially as described. 1

2. A plate for the purposes described, provided in its working face with oil-conducting grooves or cavities communicating with the opposite or exterior portion of the plate, a packing-groove in said working face exterior to and completely inclosing or encircling the said oil-conducting grooves or cavities and out of communication with the opposite face ALBERT 0. SMITH.
